Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 OVERVIEW Manual This manual is designed to assist in the installation, operation, and maintenance of Rosemount 644 head mount and 644 rail mount. Section 1: Introduction • Transmitter and Manual Overview • Considerations • Return of Material Section 2: Installation • Mounting • Installation • Wiring • Power Supply • Commissioning Section 3: Configuration • Calibration • Hardware Maintenance • Diagnostic Messaging Appendix A: Specifications and Reference Data • Specifications • Dimensional Drawings • Ordering Information • Biotechnology, Pharmaceutical Industries, and Sanitary Applications Appendix B: Product Certifications • Product Certifications • Installation Drawings Appendix C: Foundation fieldbus Block Information • Transmitter 1-2 Information regarding the Function Blocks Features of the Rosemount 644 include: • Accepts inputs from a wide variety of sensors • Configuration using FOUNDATION fieldbus • Electronics that are completely encapsulated in epoxy and enclosed in a metal housing, making the transmitter extremely durable and ensuring long-term reliability • A compact size and two housing options allowing mounting flexibility for the control room or the field Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Refer to the following literature for a full range of compatible connection heads, sensors, and thermowells provided by Emerson Process Management. • Temperature Sensors and Assemblies Product Data Sheet, Volume 1 (document number 00813-0100-2654) • Temperature Sensors and Assemblies Product Data Sheet, Volume 2 (document number 00813-0200-2654) CONSIDERATIONS General Electrical temperature sensors such as RTDs and thermocouples produce low-level signals proportional to their sensed temperature. The 644 converts the low-level sensor signal to a standard 4–20 mA dc, or digital FOUNDATION fieldbus signal that is relatively insensitive to lead length and electrical noise. This signal is then transmitted to the control room via two wires. Commissioning The transmitter can be commissioned before or after installation. It may be useful to commission it on the bench, before installation, to ensure proper operation and to become familiar with its functionality. Make sure the instruments in the loop are installed in accordance with intrinsically safe, FISCO, or non-incendive field wiring practices. Mechanical Location When choosing an installation location and position, take into account the need for access to the transmitter. Special Mounting Special mounting hardware is available for mounting a 644 head mount transmitter to a DIN rail or assembling a new 644 head mount to an existing threaded sensor connection head (former option code L1). Electrical Proper electrical installation is necessary to prevent errors due to sensor lead resistance and electrical noise. For best results, shielded cable should be used in electrically noisy environments. Make wiring connections through the cable entry in the side of the connection head. Be sure to provide adequate clearance for cover removal. Environmental The transmitter electronics module is permanently sealed within the housing, resisting moisture and corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications. Temperature Effects The transmitter will operate within specifications for ambient temperatures between –40 and 185 °F (–40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter housing. If the expected process temperature is near or beyond specification limits, consider the use of additional thermowell lagging, and extension nipple, or a remote mounting configuration to isolate the transmitter from the process. Figure 1-1 provides an example of the relationship between transmitter housing temperature rise and extension length. 1-3 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Figure 1-1. 644 head mount Transmitter Connection Head Temperature Rise vs. Extension Length Housing Temperature Rise, Above Ambient °C (°F) 60 (108) 50 (90) 40 (72) 815 °C (1500 °F) Oven Temperature 30 (54) 22 20 (36) 540 °C (1000 °F) Oven Temperature 10 (18) 250 °C (482 °F) Oven Temperature 0 3 4 3.6 5 6 7 8 Extension Length (in.) 9 Example The transmitter specification limit is 85 °C. If the ambient temperature is 55 °C and the process temperature to be measured is 800 °C, the maximum permissible connection head temperature rise is the transmitter specification limit minus the ambient temperature (moves 85 to 55 °C), or 30 °C. In this case, an extension of 100 mm meets this requirement, but 125 mm provides a margin of 8 °C, thereby reducing any temperature effects in the transmitter.

Transmitters ordered with the LCD display are shipped with the meter installed. After-market installation of the meter can be performed if the transmitter has a meter connector (transmitter revision 5.5.2 or later). After-market installation requires the meter kit (part number 00644-4430-0001), which includes: • LCD display assembly (includes LCD display, meter spacer, and 2 screws) • Meter cover with O-ring in place Figure 2-4. Installing the LCD Display Captive Mounting Screws and Springs Meter Spacer 644H 10 pin Connector LCD Display Use the following procedure to install the meter. 1. If the transmitter is installed in a loop, secure the loop and disconnect the power. If the transmitter is installed in an enclosure, remove the cover from the enclosure. 2. Decide meter orientation (the meter can be rotated in 90° increments). To change meter orientation, remove the screws located above and below the display screen. Lift the meter off the meter spacer. Remove the 8-pin plug and re-insert it in the location that will result in the desired viewing orientation. 3. Reattach the meter to the meter spacer using the screws. If the meter was rotated 90° from its original position, it will be necessary to remove the screws from their original holes and re-insert them in the adjacent screw’s holes. 4. Line up the 10-pin connector with the 10-pin socket and push the meter into the transmitter until it snaps into place. 5. Attach the meter cover; tighten at least one-third turn after the O-ring contacts the transmitter housing. The cover must be fully engaged to meet explosion-proof requirements. 6. Use a Field Communicator, AMS software, or a FOUNDATION fieldbus Communication tool to configure the meter to the desired display. NOTE Observe the following LCD display temperature limits: Operating: –4 to 185 °F (–20 to 85 °C) Storage: –50 to 185 °F (–45 to 85 °C) 2-6 Reference Manual 00809-0400-4728, Rev AA June 2011 WIRING Rosemount 644 All power to the transmitter is supplied over the signal wiring. Use ordinary copper wire of sufficient size to ensure that the voltage across the transmitter power terminals does not drop below 9 Vdc. If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals. NOTE Do not apply high voltage (e.g., ac line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit. (Sensor and transmitter power terminals are rated to 42.4 Vdc. A constant 42.4 volts across the sensor terminals may damage the unit.) The transmitters will accept inputs from a variety of RTD and thermocouple types. Refer to Figure 2-5 on page 2-7 when making sensor connections. Refer to Figure 2-6 on page 2-8 for FOUNDATION fieldbus installations. Use the following steps to wire the power and sensor to the transmitter: 1. Remove the terminal block cover (if applicable). 2. Connect the positive power lead to the “+” terminal. Connect the negative power lead to the “–” terminal (see Figure 2-7). 3. Tighten the terminal screws. When tightening the sensor and power wires, the max torque is 6-in.-lbs (0.7 N-m). 4. Reattach and tighten the cover (if applicable). 5. Apply power (see “Power Supply”). Figure 2-5.

Sensor Wiring Diagrams Power/ Signal Wiring The 644 is compatible with a number of RTD and thermocouple sensor types. Figure 2-7 shows the correct input connections to the sensor terminals on the transmitter. To ensure a proper sensor connection, anchor the sensor lead wires into the appropriate compression terminals and tighten the screws. 644 Sensor Connections Diagram 1234 2-wire RTD and 1234 3-wire RTD* and 1234 4-wire RTD and 1234 T/C and mV * Emerson Process Management provides 4-wire sensors for all single element RTDs. Use these RTDs in 3-wire configurations by leaving the unneeded leads disconnected and insulated with electrical tape. Thermocouple or Millivolt Inputs The thermocouple can be connected directly to the transmitter. Use appropriate thermocouple extension wire if mounting the transmitter remotely from the sensor. Make millivolt inputs connections with copper wire. Use shielding for long runs of wire. 2-8 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 RTD or Ohm Inputs The transmitters will accept a variety of RTD configurations, including 2-wire, 3-wire, or 4-wire. If the transmitter is mounted remotely from a 3-wire or 4-wire RTD, it will operate within specifications, without recalibration, for lead wire resistances of up to 60 ohms per lead (equivalent to 6,000 feet of 20 AWG wire). In this case, the leads between the RTD and transmitter should be shielded. If using only two leads, both RTD leads are in series with the sensor element, so significant errors can occur if the lead lengths exceed three feet of 20 AWG wire (approximately 0.05 °C/ft). For longer runs, attach a third or fourth lead as described above. Sensor Lead Wire Resistance Effect– RTD Input When using a 4-wire RTD, the effect of lead resistance is eliminated and has no impact on accuracy. However, a 3-wire sensor will not fully cancel lead resistance error because it cannot compensate for imbalances in resistance between the lead wires. Using the same type of wire on all three lead wires will make a 3-wire RTD installation as accurate as possible. A 2-wire sensor will produce the largest error because it directly adds the lead wire resistance to the sensor resistance. For 2- and 3-wire RTDs, an additional lead wire resistance error is induced with ambient temperature variations. The table and the examples shown below help quantify these errors. Table 2-1. Examples of Approximate Basic Error Sensor Input Approximate Basic Error 4-wire RTD 3-wire RTD None (independent of lead wire resistance) ± 1.0 in reading per ohm of unbalanced lead wire resistance (Unbalanced lead wire resistance = maximum imbalance between any two leads.) 1.0 in reading per ohm of lead wire resistance 2-wire RTD Examples of Approximate Lead Wire Resistance Effect Calculations Given: Total cable length: Imbalance of the lead wires at 20 °C: Resistance/length (18 AWG Cu): Temperature coefficient of Cu (Cu): Temperature coefficient of Pt(Pt): Change in Ambient Temperature (Tamb): RTD Resistance at 0 °C (Ro): 150 m 1.5 0.025 /m °C 0.039 / °C 0.00385 / °C 25 °C 100 (for Pt 100 RTD) • Pt100 4-wire RTD: No lead wire resistance effect. • Pt100 3-wire RTD: Imbalance of Lead Wires Basic Error = ----------------------------------------------------------------- Pt R o Cu T amb Imbalance of Lead Wires Error due to amb. temp. variation = ----------------------------------------------------------------------------------------------------------------------- Pt R o 2-9 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Lead wire imbalance seen by the transmitter = 0.5 0.5 Basic error = --------------------------------------------------------------------------------- = 1.3 C 0.00385 / C 100 Error due to amb. temp. var. of 25 °C 0.0039 / C 25 C 0.5 = ------------------------------------------------------------------------------------------------------- = 0.1266C 0.00385 / C 100 • Pt100 2-wire RTD: Lead Wire Resistance Basic Error = -------------------------------------------------------- Pt R o Cu T amb Lead Wire Resistance Error due to amb. temp. variation = --------------------------------------------------------------------------------------------------------------- Pt R o Lead wire resistance seen by the transmitter = 150 m × 2 wires × 0.025 /m = 7.5 7.5 Basic error = --------------------------------------------------------------------------------- = 19.5 C 0.00385 / C 100 Error due to amb. temp. var. of 25 °C 0.0039 / C 25 C 7.5 = ------------------------------------------------------------------------------------------------------- = 1.9 C 0.00385 / C 100 2-10 Reference Manual 00809-0400-4728, Rev AA June 2011 POWER SUPPLY Rosemount 644 FOUNDATION fieldbus Installation Powered over FOUNDATION fieldbus with standard fieldbus power supplies. The transmitter operates between 9.0 and 32.0 Vdc, 11 mA maximum. Transmitter power terminals are rated to 42.4 Vdc. The power terminals on the 644 with FOUNDATION fieldbus are polarity insensitive. Ground the Transmitter The transmitter will operate with the current signal loop either floating or grounded. However, the extra noise in floating systems affects many types of readout devices. If the signal appears noisy or erratic, grounding the current signal loop at a single point may solve the problem. The best place to ground the loop is at the negative terminal of the power supply. Do not ground the current signal loop at more than one point. The transmitter is electrically isolated to 500 Vdc/ac rms (707 Vdc), so the input circuit may also be grounded at any single point. When using a grounded thermocouple, the grounded junction serves as this point. Neither side of the loop should be grounded on FOUNDATION fieldbus devices. Only the shield wire should be grounded. NOTE Do not ground the signal wire at both ends. Ungrounded Thermocouple, mV, and RTD/Ohm Inputs Each process installation has different requirements for grounding. Use the grounding options recommended by the facility for the specific sensor type or begin with grounding Option 1 (the most common). Option 1: 1. Connect signal wiring shield to the sensor wiring shield. 2. Ensure the two shields are tied together and electrically isolated from the transmitter housing. 3. Ground shield at the power supply end only. 4. Ensure that the sensor shield is electrically isolated from the surrounding grounded fixtures.

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that potentially raises safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol. Warnings Failure to follow these installation guidelines could result in death or serious injury. • Make sure only qualified personnel perform the installation. Explosions could result in death or serious injury. • Do not remove the connection head cover in explosive atmospheres when the circuit is live. • Before powering a FOUNDATION fieldbus segment in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. • Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications. • All connection head covers must be fully engaged to meet explosion-proof requirements. Process leaks could result in death or serious injury. • Do not remove the thermowell while in operation. • Install and tighten thermowells and sensors before applying pressure. Electrical shock could cause death or serious injury. • www.rosemount.com Use extreme caution when making contact with the leads and terminals. Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 GENERAL BLOCK INFORMATION Device Description Before configuring the device, ensure the host has the appropriate Device Description file revision for this device. The device descriptor can be found on www.rosemount.com. The initial release of the Rosemount 644 with FOUNDATION fieldbus protocol is device revision 1. Node Address The transmitter is shipped at a temporary (248) address. This will enable FOUNDATION fieldbus host systems to automatically recognize the device and move it to a permanent address. Modes The Resource, Transducer, and all function blocks in the device have modes of operation. These modes govern the operation of the block. Every block supports both automatic (AUTO) and out of service (OOS) modes. Other modes may also be supported. Changing Modes To change the operating mode, set the MODE_BLK.TARGET to the desired mode. After a short delay, the parameter MODE_BLOCK.ACTUAL should reflect the mode change if the block is operating properly. Permitted Modes It is possible to prevent unauthorized changes to the operating mode of a block. To do this, configure MODE_BLOCK.PERMITTED to allow only the desired operating modes. It is recommended to always select OOS as one of the permitted modes. Types of Modes For the procedures described in this manual, it will be helpful to understand the following modes: AUTO The functions performed by the block will execute. If the block has any outputs, these will continue to update. This is typically the normal operating mode. Out of Service (OOS) The functions performed by the block will not execute. If the block has any outputs, these will typically not update and the status of any values passed to downstream blocks will be “BAD.” To make some changes to the configuration of the block, change the mode of the block to OOS. When the changes are complete, change the mode back to AUTO. MAN In this mode, variables that are passed out of the block can be manually set for testing or override purposes. Other Types of Modes Other types of modes are Cas, RCas, ROut, IMan, and LO. Some of these may be supported by different function blocks in the 644. For more information, see the Function Block manual (document number 00809-0100-4783). 3-2 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 NOTE When an upstream block is set to OOS, this will impact the output status of all downstream blocks. The figure below depicts the hierarchy of blocks: Resource Block Link Active Scheduler Transducer Block Analog Input (AI Block) Other Function Blocks The 644 can be designated to act as the backup Link Active Scheduler (LAS) in the event that the designated LAS is disconnected from the segment. As the backup LAS, the 644 will take over the management of communications until the host is restored. The host system may provide a configuration tool specifically designed to designate a particular device as a backup LAS. Otherwise, this can be configured manually as follows: 1. 2. Block Installation Access the Management Information Base (MIB) for the 644. To activate the LAS capability, write 0x02 to the BOOT_OPERAT_FUNCTIONAL_CLASS object (Index 605). To deactivate, write 0x01. Restart the device. Rosemount devices are pre-configured with function blocks at the factory, the default permanent configuration for the 644 is listed below. The 644 can have up to ten additional instantiated function blocks. • 2 Analog Input Blocks (tag names AI 1300, AI 1400) • 1 Proportional/Integral/Derivative Block (tag name PID 1500) The 644 supports the use of Function Block Instantiation. When a device supports block instantiation, the number of blocks and block types can be defined to match specific application needs.The number of blocks that can be instantiated is only limited by the amount of memory within the device and the block types that are supported by the device. Instantiation does not apply to standard device blocks like the Resource, Sensor Transducer, LCD Transducer, and Advanced Diagnostics Blocks. By reading the parameter “FREE_SPACE” in the Resource block you can determine how many blocks you can instantiate. Each block that you instantiate takes up 4.5% of the “FREE_SPACE.” Block instantiation is done by the host control system or configuration tool, but not all hosts are required to implement this functionality. Please refer to your specific host or configuration tool manual for more information. 3-3 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Capabilities Virtual Communication Relationship (VCRs) There are a total of 12 VCRs. One is permanent and 11 are fully configurable by the host system. Sixteen link objects are available.

Reference information on the PID block can be found in the Function Block manual document number 00809-0100-4783. Resource Block (index number 1000) The Resource Function Block (RB) contains diagnostic, hardware, and electronics information. There are no linkable inputs or outputs to the Resource Block. Sensor Transducer Block (index number 1100) The Sensor Transducer Function Block (STB) temperature measurement data includes sensor and terminal temperature. The STB also includes information about sensor type, engineering units, linearization, reranging, damping, temperature compensation, and diagnostics. LCD Transducer Block (index number 1200) The LCD Transducer Block is used to configure the LCD meter. Analog Input Block (index number 1300 and 1400) The Analog Input Function Block (AI) processes the measurements from the sensor and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The AI block is widely used for scaling functionality. PID Block (index number 1500) The PID Function Block combines all of the necessary logic to perform proportional/integral/derivative (PID) control. The block supports mode control, signal scaling and limiting, feed forward control, override tracking, alarm limit detection, and signal status propagation. 3-4 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 The block supports two forms of the PID equation: Standard and Series. You can choose the appropriate equation using the MATHFORM parameter. The Standard ISA PID equation is the default selection. Resource Block FEATURES and FEATURES_SEL The parameters FEATURES and FEATURE_SEL determine optional behavior of the 644. FEATURES The FEATURES parameter is read only and defines which features are supported by the 644. Below is a list of the FEATURES the 644 supports. UNICODE All configurable string variables in the 644, except tag names, are octet strings. Either ASCII or Unicode may be used. If the configuration device is generating Unicode octet strings, you must set the Unicode option bit. REPORTS The 644 supports alert reports. The Reports option bit must be set in the features bit string to use this feature. If it is not set, the host must poll for alerts. SOFT W LOCK Inputs to the security and write lock functions include the software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK parameter. The WRITE_LOCK parameter prevents modification of parameters within the device except to clear the WRITE_LOCK parameter. During this time, the block will function normally updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI parameter. The FEATURE_SEL parameter enables the user to select the software write lock or no write lock capability. In order to enable the software write lock, the SOFT_W_LOCK bit must be set in the FEATURE_SEL parameter. Once this bit is set, the WRITE_LOCK parameter may be set to “Locked” or “Unlocked.” Once the WRITE_LOCK parameter is set to “Locked” by the software, all user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be rejected. The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock function will control writing to all blocks, or only to the resource and transducer blocks. Internally updated data such as process variables and diagnostics will not be restricted. N/A = No blocks are blocked Physical = Locks resource and transducer block Everything = Locks every block. 3-5 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 The following table displays all possible configurations of the WRITE_LOCK parameter. FEATURE_SEL SW_SEL bit WRITE_LOCK WRITE_LOCK Read/Write Write access DEFINE_WRITE_LOCK to blocks 0 (off) 1 (on) 1 (on) 1 (unlocked) 1 (unlocked) 2 (locked) Read only Read/Write Read/Write NA NA Physical 1 (on) 2 (locked) Read/Write Everything All All Function Blocks only None FEATURES_SEL FEATURES_SEL is used to turn on any of the supported features. The default setting of the 644 does not select any of these features. Choose one of the supported features if any. MAX_NOTIFY The MAX_NOTIFY parameter value is the maximum number of alert reports that the resource can have sent without getting a confirmation, corresponding to the amount of buffer space available for alert messages. The number can be set lower, to control alert flooding, by adjusting the LIM_NOTIFY parameter value. If LIM_NOTIFY is set to zero, then no alerts are reported. PlantWeb™ Alerts The alerts and recommended actions should be used in conjunction with “Operation and Maintenance” on page 3-15. The Resource Block will act as a coordinator for PlantWeb alerts. There will be three alarm parameters (FAILED_ALARM, MAINT_ALARM, and ADVISE_ALARM) which will contain information regarding some of the device errors which are detected by the transmitter software. There will be a RECOMMENDED_ACTION parameter which will be used to display the recommended action text for the highest priority alarm and a HEALTH_INDEX parameters (0 - 100) indicating the overall health of the transmitter. FAILED_ALARM will have the highest priority followed by MAINT_ALARM and ADVISE_ALARM will be the lowest priority. FAILED_ALARMS A failure alarm indicates a failure within a device that will make the device or some part of the device non-operational. This implies that the device is in need of repair and must be fixed immediately. There are five parameters associated with FAILED_ALARMS specifically, they are described below. FAILED_ENABLED This parameter contains a list of failures in the device which makes the device non-operational that will cause an alert to be sent. Below is a list of the failures with the highest priority first. 1. 2. 3. 4. 5. 3-6 Electronics NV Memory HW / SW Incompatible Primary Value Secondary Value Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 FAILED_MASK This parameter will mask any of the failed conditions listed in FAILED_ENABLED. A bit on means that the condition is masked out from alarming and will not be reported. FAILED_PRI Designates the alerting priority of the FAILED_ALM, see “Alarm Priority” on page 3-13. The default is 0 and the recommended value are between 8 and 15. FAILED_ACTIVE This parameter displays which of the alarms is active. Only the alarm with the highest priority will be displayed. This priority is not the same as the FAILED_PRI parameter described above. This priority is hard coded within the device and is not user configurable. FAILED_ALM Alarm indicating a failure within a device which makes the device non-operational. MAINT_ALARMS A maintenance alarm indicates the device or some part of the device needs maintenance soon. If the condition is ignored, the device will eventually fail. There are five parameters associated with MAINT_ALARMS, they are described below. MAINT_ENABLED The MAINT_ENABLED parameter contains a list of conditions indicating the device or some part of the device needs maintenance soon. Below is a list of the conditions with the highest priority first. 1. 2. 3. 4. 5. Primary Value Degraded Secondary Value Degraded Diagnostic Configuration Error Calibration Error MAINT_MASK The MAINT_MASK parameter will mask any of the failed conditions listed in MAINT_ENABLED. A bit on means that the condition is masked out from alarming and will not be reported. MAINT_PRI MAINT_PRI designates the alarming priority of the MAINT_ALM, “Process Alarms” on page 3-12. The default is 0 and the recommended values is 3 to 7. MAINT_ACTIVE The MAINT_ACTIVE parameter displays which of the alarms is active. Only the condition with the highest priority will be displayed. This priority is not the same as the MAINT_PRI parameter described above. This priority is hard coded within the device and is not user configurable. MAINT_ALM An alarm indicating the device needs maintenance soon. If the condition is ignored, the device will eventually fail. 3-7 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Advisory Alarms An advisory alarm indicates informative conditions that do not have a direct impact on the device's primary functions. There are five parameters associated with ADVISE_ALARMS. They are described below. ADVISE_ENABLED The ADVISE_ENABLED parameter contains a list of informative conditions that do not have a direct impact on the device's primary functions. Below is a list of the advisories with the highest priority first. 1. 2. NV Writes Deferred SPM Process Anomaly detected ADVISE_MASK The ADVISE_MASK parameter will mask any of the failed conditions listed in ADVISE_ENABLED. A bit on means the condition is masked out from alarming and will not be reported. ADVISE_PRI ADVISE_PRI designates the alarming priority of the ADVISE_ALM, see “Process Alarms” on page 3-12. The default is 0 and the recommended values are 1 or 2. ADVISE_ACTIVE The ADVISE_ACTIVE parameter displays which of the advisories is active. Only the advisory with the highest priority will be displayed. This priority is not the same as the ADVISE_PRI parameter described above. This priority is hard coded within the device and is not user configurable. ADVISE_ALM ADVISE_ALM is an alarm indicating advisory alarms. These conditions do not have a direct impact on the process or device integrity. Recommended Actions for PlantWeb Alerts RECOMMENDED_ACTION The RECOMMENDED_ACTION parameter displays a text string that will give a recommended course of action to take based on which type and which specific event of the PlantWeb alerts are active. 3-8 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Table 3-1.

THIS IS THE ONLY WAY TO CHANGE THE ENGINEERING UNITS IN THE SENSOR TRANSDUCER BLOCK. Damping The damping parameter in the Transducer Block may be used to filter measurement noise. By increasing the damping time, the transmitter will have a slower response time, but will decrease the amount of process noise that is translated to the Transducer Block Primary Value. Because both the LCD and AI Block get input from the Transducer Block, adjusting the damping parameter will effect both blocks. NOTE The AI Block has it's own filtering parameter called PV_FTIME. For simplicity, it is better to do filtering in the Transducer Block as damping will be applied to primary value on every sensor update. If filtering is done in AI block, damping will be applied to output every macrocycle. The LCD will display value from Transducer block. Analog Input (AI) Function Block Configure the AI block A minimum of four parameters are required to configure the AI Block. The parameters are described below with example configurations shown at the end of this section. CHANNEL Select the channel that corresponds to the desired sensor measurement. The 644 measures both sensor temperature (channel 1) and terminal temperature (channel 2). 3-9 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 L_TYPE The L_TYPE parameter defines the relationship of the sensor measurement (sensor temperature) to the desired output temperature of the AI Block. The relationship can be direct or indirect. Direct Select direct when the desired output will be the same as the sensor measurement (sensor temperature). Indirect Select indirect when the desired output is a calculated measurement based on the sensor measurement (e.g. ohm or mV). The relationship between the sensor measurement and the calculated measurement will be linear. XD_SCALE and OUT_SCALE The XD_SCALE and OUT_SCALE each include four parameters: 0%, 100%, engineering units, and precision (decimal point). Set these based on the L_TYPE: L_TYPE is Direct When the desired output is the measured variable, set the XD_SCALE to represent the operating range of the process. Set OUT_SCALE to match XD_SCALE. L_TYPE is Indirect When an inferred measurement is made based on the sensor measurement, set the XD_SCALE to represent the operating range that the sensor will see in the process. Determine the inferred measurement values that correspond to the XD_SCALE 0 and 100% points and set these for the OUT_SCALE. NOTE To avoid configuration errors, only select Engineering Units for XD_SCALE and OUT_SCALE that are supported by the device. The supported units are: Pressure (Channel 1) Temperature (Channel 2) °C °F K R mV °C °F K R mV When the engineering units of the XD_SCALE are selected, this causes the engineering units of the PRIMARY_VALUE_RANGE in the Transducer Block to change to the same units. THIS IS THE ONLY WAY TO CHANGE THE ENGINEERING UNITS IN THE SENSOR TRANSDUCER BLOCK, PRIMARY_VALUE_RANGE parameter. 3-10 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Configuration Examples 4-wire, Pt 100 = 385 AI1 = Process Temperature AI2 = Terminal Temperature Transducer Block If Host System Supports Methods: 1.

Adjust the filter time constant (in seconds) using the PV_FTIME parameter. Set the filter time constant to zero to disable the filter feature. Process Alarms Process Alarm detection is based on the OUT value. Configure the alarm limits of the following standard alarms: • High (HI_LIM) • High high (HI_HI_LIM) • Low (LO_LIM) • Low low (LO_LO_LIM) In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters: 3-12 • HI_PRI • HI_HI_PRI • LO_PRI • LO_LO_PRI Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Alarm Priority Alarms are grouped into five levels of priority: Priority Number 0 1 2 3-7 8-15 Priority Description The alarm condition is not used. An alarm condition with a priority of 1 is recognized by the system, but is not reported to the operator. An alarm condition with a priority of 2 is reported to the operator. Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority. Alarm conditions of priority 8 to 15 are critical alarms of increasing priority. Status Options Status Options (STATUS_OPTS) supported by the AI block are shown below: Propagate Fault Forward If the status from the sensor is Bad, Device failure or Bad, Sensor failure, propagate it to OUT without generating an alarm. The use of these sub-status in OUT is determined by this option. Through this option, the user may determine whether alarming (sending of an alert) will be done by the block or propagated downstream for alarming. Uncertain if Limited Set the output status of the Analog Input block to uncertain if the measured or calculated value is limited. BAD if Limited Set the output status to Bad if the sensor is violating a high or low limit. Uncertain if Man Mode Set the output status of the Analog Input block to uncertain if the actual mode of the block is Man. NOTE The instrument must be in Out of Service mode to set the status option. Advanced Features The AI Function Block provides added capability through the addition of the following parameters: ALARM_TYPE ALARM_TYPE allows one or more of the process alarm conditions detected by the AI function block to be used in setting its OUT_D parameter. OUT_D OUT_D is the discrete output of the AI function block based on the detection of process alarm condition(s). This parameter may be linked to other function blocks that require a discrete input based on the detected alarm condition. 3-13 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 LCD Transducer Block The LCD meter connects directly to the 644 electronics FOUNDATION fieldbus output board. The meter indicates output and abbreviated diagnostic messages. The first line of five characters displays the sensor being measured. If the measurement is in error, “Error” appears on the first line. The second line indicates if the device or the sensor is causing the error. Each parameter configured for display will appear on the LCD for a brief period before the next parameter is displayed. If the status of the parameter goes bad, the LCD will also cycle diagnostics following the displayed variable. Custom Meter Configuration Shipped from the factory, Parameter #1 is configured to display the Primary Variable (temperature) from the LCD Transducer Block. Parameters 2 – 4 are not configured. To change the configuration of Parameter #1 or to configure additional parameters 2 – 4, use the configuration parameters below. The LCD Transducer Block can be configured to sequence four different process variables as long as the parameters are sourced from a function block that is scheduled to execute within the 644 temperature transmitter. If a function block is scheduled in the 644 that links a process variable from another device on the segment, that process variable can be displayed on the LCD. DISPLAY_PARAM_SEL The DISPLAY_PARAM_SEL parameter specifies how many process variables will be displayed. Select up to four display parameters. BLK_TAG_#(1) Enter the Block Tag of the function block that contains the parameter to be displayed. The default function block tags from the factory are: TRANSDUCER AI 1300 AI 1400 PID 1500 BLK_TYPE_#(1) Enter the Block Type of the function block that contains the parameter to be displayed. This parameter is generally selected via a drop-down menu with a list of possible function block types. (e.g. Transducer, PID, AI, etc.) PARAM_INDEX_#(1) The PARAM_INDEX_# parameter is generally selected via a drop-down menu with a list of possible parameter names based upon what is available in the function block type selected. Choose the parameter to be displayed. CUSTOM_TAG_#(1) The CUSTOM_TAG_# is an optional user-specified tag identifier that can be configured to be displayed with the parameter in place of the block tag. Enter a tag of up to five characters. (1) 3-14 # represents the specified parameter number. Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 UNITS_TYPE_#(1) The UNITS_TYPE_# parameter is generally selected via a drop-down menu with three options: AUTO, CUSTOM, or NONE. Select AUTO only when the parameter to be displayed is pressure, temperature, or percent. For other parameters, select CUSTOM and be sure to configure the CUSTOM_UNITS_# parameter. Select NONE if the parameter is to be displayed without associated units. CUSTOM_UNITS_#(1) Specify custom units to be displayed with the parameter. Enter up to six characters. To display Custom Units the UNITS_TYPE_# must be set to CUSTOM. OPERATION AND MAINTENANCE Overview This section contains information on operation and maintenance procedures. METHODS AND MANUAL OPERATION Each FOUNDATION fieldbus host or configuration tool has different ways of displaying and performing operations. Some hosts will use Device Descriptions (DD) and DD Methods to complete device configuration and will display data consistently across platforms. The DD can found on www.rosemount.com. There is no requirement that a host or configuration tool support these features. The information in this section will describe how to use methods in a general fashion. In addition, if your host or configuration tool does not support methods this section will cover manually configuring the parameters involved with each method operation. For more detailed information on the use of methods, see your host or configuration tool manual. 3-15 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Troubleshooting Guides Figure 3-1. 644 troubleshooting flowchart PROBLEMS WITH COMMUNICATIONS Device does not stay on segment.

If your system does not support methods, manually configure the Transducer Block parameters listed below. 1. 2. 3. 4. 5. 6. 7. 8. Set MODE_BLK.TARGET to OOS. Set SENSOR_CAL_METHOD to User Trim. Set CAL_UNIT to supported engineering units in the Transducer Block. Apply temperature that corresponds to the lower calibration point and allow the temperature to stabilize. The temperature must be between the range limits defined in PRIMRY_VALUE_RANGE. Set values of CAL_POINT_LO to correspond to the temperature applied by the sensor. Apply temperature, temperature corresponding to the upper calibration. Allow temperature to stabilize. Set CAL_POINT_HI. NOTE CAL_POINT_HI must be within PRIMARY_VALUE_RANGE and greater than CAL_POINT_LO + CAL_MIN_SPAN 9. Set SENSOR_CAL_DATE to the current date. 10. Set SENSOR_CAL_WHO to the person responsible for the calibration. 11. Set SENSOR _CAL_LOC to the calibration location. 12. Set MODE_BLK.TARGET to AUTO. NOTE If trim fails, the transmitter will automatically revert to factory trim. Excessive correction or sensor failure could cause device status to read “calibration error.” To clear this, trim the transmitter. 3-18 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Recall Factory Trim To recall a factory trim on the transmitter, run the Recall Factory Trim. If your system does not support methods, manually configure the Transducer Block parameters listed below. 1. 2. 3. 4. 5. 6. 7. Set MODE_BLK.TARGET to OOS. Set SENSOR_CAL_METHOD to Factory Trim. Set SET_FACTORY_TRIM to Recall. Set SENSOR_CAL_DATE to the current date. Set SENSOR_CAL_WHO to the person responsible for the calibration. Set SENSOR _CAL_LOC to the calibration location. Set MODE_BLK.TARGET to AUTO. NOTE When sensor type is changed, the transmitter reverts to the factory trim. Changing sensor type causes you to loose any trim performed on the transmitter. Table 3-3.

The PV and STATUS are passed from the Transducer Block to the Analog Input Block. The STATUS can be one of the following: GOOD, BAD, or UNCERTAIN. When there are no problems detected by the self-diagnostics of the block, the STATUS will be GOOD. If a problem occurs with the hardware in the device or the quality of the process variable is compromised for some reason, the STATUS will become either BAD or UNCERTAIN depending upon the nature of the problem. It is important that the Control Strategy that makes use of the Analog Input Block is configured to monitor the STATUS and take action where appropriate when the STATUS is no longer GOOD. Simulation Simulate replaces the channel value coming from the Sensor Transducer Block. For testing purposes, it is possible to manually drive the output of the Analog Input Block to a desired value. There are two ways to do this. Manual Mode To change only the OUT_VALUE and not the OUT_STATUS of the AI Block, place the TARGET MODE of the block to MANUAL. Then, change the OUT_VALUE to the desired value. Simulate 1. If the SIMULATE switch is in the OFF position, move it to the ON position. If the SIMULATE jumper is already in the ON position, you must move it to off and place it back in the ON position. NOTE As a safety measure, the switch must be reset every time power is interrupted to the device in order to enable SIMULATE. This prevents a device that is tested on the bench from getting installed in the process with SIMULATE still active. 2. 3. 4. To change both the OUT_VALUE and OUT_STATUS of the AI Block, set the TARGET MODE to AUTO. Set SIMULATE_ENABLE_DISABLE to ‘Active.’ Enter the desired SIMULATE_VALUE to change the OUT_VALUE and SIMULATE_STATUS_QUALITY to change the OUT_STATUS. If errors occur when performing the above steps, be sure that the SIMULATE jumper has been reset after powering up the device. 3-21 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 Table 3-6.

Advanced manufacturing techniques and the use of Statistical Process Control provide specification conformance to at least ± 3(1). Our commitment to continual improvement ensures that product design, reliability, and performance will improve annually. Lower Specification Limit For example, the Reference Accuracy distribution for the 644 is shown to the right. Our Specification Limits are ± 0.15 °C, but, as the shaded area shows, approximately 68% of the units perform three times better than the limits. Therefore, it is very likely that you will receive a device that performs much better than our published specifications. –3 Conversely, a vendor who “grades” product without using Process Control, or who is not committed to ± 3 performance, will ship a higher percentage of units that are barely within advertised specification limits. –2 Upper Specification Limit –1 1 2 3 Accuracy distribution shown is for the 644, Pt 100 RTD sensor, Range 0 to 100 °C (1) Sigma () is a statistical symbol to designate the standard deviation from the mean value of a normal distribution. FOUNDATION FIELDBUS SPECIFICATIONS A-4 Function Blocks Resource Block • The resource block contains physical transmitter information including available memory, manufacture identification, device type, software tag, and unique identification. Transducer Block • The transducer block contains the actual temperature measurement data, including sensor 1 and terminal temperature. It includes information about sensor type and configuration, engineering units, linearization, reranging, damping, temperature correction, and diagnostics. LCD Block • The LCD block is used to configure the local display, if an LCD Display is being used. Analog Input (AI) • Processes the measurement and makes it available on the fieldbus segment. • Allows filtering, alarming, and engineering unit changes. PID Block • The transmitter provides control functionality with one PID function block in the transmitter. The PID block can be used to perform single loop, cascade, or feedforward control in the field. Instantiable Function Blocks • All the function blocks used by the transmitter are instantiable, meaning the total number of function blocks is only limited by the physical memory available in the transmitter. Since only the instantiable blocks can use physical memory, any combination of function blocks can be used at any given time as long as the physical memory size is not violated.

Status If self-diagnostics detect a sensor burnout or a transmitter failure, the status of the measurement will be updated accordingly. Status may also send the PID output to a safe value. Power Supply Powered over FOUNDATION fieldbus with standard fieldbus power supplies. The transmitter operates between 9.0 and 32.0 Vdc, 11 mA maximum. The power terminals are rated to 42.4 Vdc max. Alarms The AI function block allows the user to configure the alarms to HI-HI, HI, LO, or LO-LO with a variety of priority levels and hysteresis settings. Backup Link Active Scheduler (LAS) The transmitter is classified as a device link master, which means it can function as a Link Active Scheduler (LAS) if the current link master device fails or is removed from the segment. The host or other configuration tool is used to download the schedule for the application to the link master device. In the absence of a primary link master, the transmitter will claim the LAS and provide permanent control for the H1 segment.

C-7 Reference Manual 00809-0400-4728, Rev AA June 2011 Rosemount 644 ANALOG INPUT (AI) FUNCTION BLOCK The Analog Input (AI) function block processes field device measurements and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes. The AI block supports alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation. In Automatic mode, the block’s output parameter (OUT) reflects the process variable (PV) value and status. In Manual mode, OUT may be set manually. The Manual mode is reflected on the output status. A discrete output (OUT_D) is provided to indicate whether a selected alarm condition is active. Alarm detection is based on the OUT value and user specified alarm limits. Figure C-1 illustrates the internal components of the AI function block, and Table C-3 lists the AI block parameters and their units of measure, descriptions, and index numbers. Figure C-1.
